WELL SHOZJTING DEVICE Filed May 28, 1930 gwuentom JJH/LL Patented Mar.31, 1931 UNITED STATES JESSE J. HILL, OF INDEPENDENCE, KANSASWELL-SHOOTING DEVICE Application filed May 28, 1930. Serial No. 456,586.

My invention relates to improvements in well shooting devices, and oneobject of my invention is the provision of a device of the character andfor the purpose stated which can be lowered with ease and safety intothe well, which can be timed to explode at a definite set moment andwhich will be positive and reliable in action and thus insure a mostdesirable and practical device for the purpose intended.

Another object of my invention is the provision of a well shootingdevice which will be composed of few parts to insure absolute certaintyin action, which cannot possibly explode until the time requiredinsuring a device which can be handled with safety and which willcontain all of its parts or'elements in a single unit or structure.

Another object of my invention is the pro- 2 vision of a well shootingdevice which will have great shattering power to obtain the bestpossible results, which can be easily packed, transported and assembledand which can be made at a small price which with other advantages willmake the device very useful and practical.

To attain the objects stated and such others as belong to a device ofthis character, my invention consists of a well shooting deviceembodying novel features of construction and combination of parts,substantially as described and claimed, and as shown in the accompanyingdrawing, in which:

Figure 1 represents a view showing the shell or casing in section andthe operating parts of my device in side elevation, and illustrating theinvention in complete form.

Figure 2 represents a face view of a clock of the type used in my wellshooting device, and

Figure 3 represents a vertical central sectional view of the acidcontaining unit or element of my device, shown on an enlarged scale. I

An important aim of my invention 'is to produce a device of themost;si1nple and inexpensive construction and in carrying my inventioninto effect, I employ a hollow casing or shell 1, having a loweredtapered or point- 50 ed end 2, and having interior threads 3, at

the mouth to be engaged by the threads 4:, on the annular flange 5, ofthe cap or closure 6, which carries the yoke 7, to which in use isattached a rope or means for lowering the shell into the Well.

The hollow shell receives the shattering charge 8 upon which is placed asuitable fulminate or explosive 9, which acts, as will presently appearto ignite and fire the main or shattering charge 9'.

Fitting in the open upper end or mouth of the shell and retained by anannular shoulder 10, is a clock 11, whose face 12, is arrangeduppermost, and to the back 13, of which is connected the yoke shapedhanger 14, having a band or collar clamp 15, which holds and suspendsthe cylindrical acid container The acid container as to structure andits relation to other parts of my invention forms a most importantfeature, and it is provided at its lower portion with a reduced openingor passage 17, a reduced threaded portion 18, which receives a threadedcap 19, having an outlet 20, and the cap retains in place the layer 21,of suitable material such as fullers earth and the screen or filter 22,while the threaded open top 23, of the container receives the threadedcap 24, having a filling opening 25, to receive the acid, and in the 30threaded opening 26, in the top is mounted the threaded portion 27 ofthe valve stem 28.

From this construction it will'be noted that from the back of the clockis suspended a hanger in which is supported an acid containing elementand that said element or container has an opening and a valve seat forthe valve stem, and the valve stem contiguous with its threaded portioncarries a bifurcated head or lug 29, which fits upon the key 30, of thealarm mechanism and when the said key turns and at a set and determinedminute by the ringing of the alarm in the well known manner, said keyturns the said head or lug 29, and also the valve stem, raising thevalve from its seat and allowing the acid from the container to passdown and through the fullers earth and to drop upon the fulminate 9, andinstantly fire the shatterin charge 9', to effect the shooting of the we1 as is obvious.

From the foregoing description taken in connection with the drawing themany advan- 5 tages of my device will be readily understood and it isnot thought necessary to elaborate thereon, but it will be apparent thatthe shell is harmless until the acid is discharged at o the determinedmoment and that it will not 1 act except at the time set, also that theentire mechamsm is contained in a single unit and can be transportedwith ease and facility and without danger,'that the shell can be easilycharged by a person of ordinary intelligence and set at a time for itsex losion in the well, that the time for the exp osion can be regulatedin the same manner as the setting of an alarm clock, that the device canbe lowered with readiness and perfect safety into the well. and that itwill never fail to explode at the time set and desired, and thatgenerally in every respect the device will prove reliable, eficient andpractical.

I claim:

at 1. In a well shooting device, the combination of a shell, a shatterincharge in said shell, a fulminate or firin c arge above said shatteringcharge for exp oding said shattering charge, a clock arranged above saidfiring so and shattering charge, and an acid containing element operatedby the clock to discharge acid on said fulminate to explode saidshattering charge. a

2. In a well shooting device, the combination of a shell, a lowerdisposed shattering charge, a surmounting fulminate or firing charge, aclock arranged in said shell above said charges, an acid containerassociated with said clock, and mechanism in said acid 4 container 0eratively connected with the alarm key 0 the clock to be operated by theturning of said key at a determined time to .drop acid on said fulminateto explode said V shattering charge.

3. In a well shooting device, the combination of a shell, a shatteringand firing charge carried in said shell, a-clock in said shell abovesaid char es, an acid container disposed in proper re tion to saidclock, a filtering me- ;o dium in said acid container, a valve forcontrolling the discharge of acid from said container, and meansconnecting said valve'with the alarm winding key of said clock to turnsaid valve to discharge the acid upon said firing charge to explode saidshattering charge.

11 testimony whereof I afix my signature.

JESSE J. HILL.
